CVE-2020-1634

Estado: ModificadaAlta (7.5)—

En los dispositivos High-End SRX Series, en configuraciones específicas y cuando se presentan eventos de red específicos o acciones del operador, puede ocurrir un SPC que reciba tráfico multidifusión genuino. Posteriormente, todos los FPC en un chasis pueden reiniciarse causando una Denegación de Servicio. Este problema afecta tanto a IPv4 como a IPv6. Este problema afecta a: Juniper Networks Junos OS versión 12.3X48 hasta 12.3X48-D80 y versiones posteriores a 12.3X48-D95 en High-End SRX Series. Este problema no afecta a los dispositivos de Branch SRX Series.
